In postmortem cases, where drugs or pesticides have been used for
their poisonous properties, traditional matrices such as urine and
whole blood may be inappropriate for qualitative and quantitative
analysis. As the site of metabolism for most drugs and toxins, the
liver may provide more insight to cause of death than other bodily
fluids.
This poster describes the use of ISOLUTE SLE+ supported liquid extraction columns to extract a range of drug and pesticide classes form homogenised liver using a simple, streamlined workflow.

The following method was developed for the extraction of barbiturate drugs from urine, including: butabarbital, amobarbital, cyclobarbital and phenobarbital. Typical recoveries for these drugs are > 85%.

This application note describes the extraction of barbiturate compounds from whole blood, prior to GC/MS analysis. This protocol also allows the simultaneous extraction of various other drugs of abuse classes: amphetamines, benzodiazepines, cocaine and opiates.
ISOLUTE® SLE+ columns with 1 mL sample capacity are used to extract whole blood samples following a straightforward sample dilution. No protein precipitation or other pre-treatment is required prior to sample loading. The sample preparation procedure delivers clean extracts, good recoveries and RSD values and LLOQs from 20 ng/mL (analyte dependant).

This application note describes the extraction of a broad range of analytes from liver tissue matrix prior to GC/MS analysis using ISOLUTE® SLE+ supported liquid extraction columns.
A protocol has been developed that allows the simultaneous
extraction of various drugs of abuse classes: amphetamines, barbiturates, benzodiazepines, cocaine, ketamine, THC.
In addition to these drug panels, simultaneous extraction of carbamate, organochlorine, organophosphate, pyrethroid, and triazine pesticide classes is demonstrated.

This poster describes a simple but effective method for screening a range of pesticides and drugs of abuse from liver samples. Liver tissue is homogenized using the Biotage® Lysera, and the subsequent extract is cleaned up using ISOLUTE SLE+ supported liquid extraction columns.
